Chapter 128 My Ultimate Erotic Magic Tool ②
Edited by: Kanaa-senpai
”So this is the ‘Wriggle Ddo-Buddy¹‘…? From what I can see, it looks like a perfectly ordinary ‘Ddo-Buddy’,” Aerith said.
”Yes, but even the ‘Tremble Ddo-Buddy²‘ looks no different from a normal one, right? Actually, this is an even more sophisticated product than the ‘Piston Machine³‘,” Satsuki explained.
”My, is that so…” Aerith replied.
At a meeting to exchange opinions on new products, Satsuki, the court mage, begins introducing the “Wriggle Ddo-Buddy” to Aerith from the Garou Merchant Guild⁴. The two of them face each other with dead-serious expressions across a single “Ddo-Buddy”. And then there’s that power word: “perfectly ordinary ‘Ddo-Buddy’”.
The feeling that this is a magnificent sight and the urge to provide a tsukkomi well up inside me alternately, but I endure. Since explaining the products was always my job, I never noticed it before, but I wonder if everyone else was enduring this itchy awkwardness and keeping a straight face for me…. Feeling strangely grateful, I listen to Satsuki’s explanation.
”The ‘Wriggle Ddo-Buddy’ is characterized by its unique ‘wriggling’ movement, as the name suggests. The secret lies in the combination of two movements: a serpentine motion and a rotational motion,” Satsuki said.
”I see, is it… something like this? ” Aerith asked.
In response to Satsuki’s commentary, Aerith uses her hands to recreate the twisting motion. Her tail is also making strange movements along with her—is that unconscious? There is still much I don’t understand about beastman ecology.
”Hehe, it’s faster to actually see it than to explain it in words. The way to operate it is the same as the ‘Tremble Ddo-Buddy’,” Satsuki said.
”Y-Yes…” Aerith replied.
Aerith gulps as she looks at the “Wriggle Ddo-Buddy” handed to her. She tilts her head, checking the shape and feel, finding it no different from a regular one. Then, with half-doubt, she presses the switch on the bottom…
Whirrr-whirrr-whirrr-whirrr…!
”Wa-wah…!” Aerith cried out.
The “Ddo-Buddy” begins to writhe. Surprised by the movement, Aerith accidentally drops it. It hits the floor with a thud and continues to move around on the ground, the mechanical drive sound echoing.
Is it some kind of new toy for cats or dogs? That’s what the movement makes me think. Ignoring the flustered Aerith, the calm Satsuki reaches down and firmly grabs it. The top half is what’s moving; if you grip the bottom half securely, you won’t drop it.
Satsuki, who is likely a virgin, has become completely accustomed to handling the “Ddo-Buddy”. At the tips of her fingers, the device continues to “wriggle” about. Hmm, I’m starting to look forward to letting customers who know nothing about this grip it!
”See, it’s alright. Try holding it just like you would when, uh, using it,” Satsuki said.
”L-Like this? O-Ohh…!” Aerith exclaimed.
”How is it? This complex movement is, um, supposed to act on the inside and provide pleasure… or so we planned,” Satsuki said, her face turning red.
Unfortunately, even Satsuki, the developer, doesn’t know the actual effect. I designed it while imagining the usual hip movements and the way people use these tools, but the truth can only be known by asking the user.
”You’re right…. I won’t know for sure until I actually try it, but my first impression is that there’s no way it wouldn’t feel good. I believe this will definitely sell as well,” Aerith said.
”R-Really!? I’m so glad. I made it while consulting Kento, but I couldn’t be certain myself…” Satsuki said, her expression showing relief.
However, Aerith is now making a difficult face while following the movement of the device with her eyes. Satsuki notices and asks a question.
”Is… is there something bothering you? ” Satsuki asked.
”No, I was just wondering if this ‘Wriggle Ddo-Buddy’ can also be attached to the ‘Piston Machine’,” Aerith replied.
”Oh, of course! Anything with the same shape as a ‘Ddo-Buddy’ can be attached,” Satsuki said.
Satsuki busily prepares the “Piston Machine” and lets Aerith attach the wriggler. Then, while repeating a chuffing up-and-down motion, the device performs its combination of serpentine and rotational movements. With three movements combined, it looks like the strongest thing ever.
Whirrr whirrr whirrr.
Chuff chuff chuff.
The surrealism is about to break through the heavens. The depth of human karma in the pursuit of pleasure is truly bottomless…. While I’m thinking that, Aerith, who hasn’t lost her serious expression even at this sight, speaks up.
”In this case, I’m worried about the durability…” Aerith said.
”Eh, ah. Right. I’ve been testing it like this, but…” Satsuki said.
As she speaks, Satsuki loosely grips the tip of the device. Needless to say, she is using her hand as a stand-in for female anatomy. She has a serious look on her face, but from the outside, it looks no different from a handjob. Aerith places her hand on top of Satsuki’s. It’s a double handjob.
”Hmm, it seems okay for now, but people get excited during use. It might also depend on the speed adjustment function of the ‘Piston Machine’,” Aerith said.
”We’ll just have to have everyone confirm it through ‘experiments’. Shall I try setting it to ‘High’ once? ” Satsuki asked.
”Yes, please,” Aerith replied.
Thump-thump-thump-thump…!
Whirrr-whirrr-whirrr…!
The device wriggles and squirms while moving up and down violently. And the two of them are being shaken while they grip the rampaging thing with serious faces. Yep, this is a sight that makes me glad I’m the owner of a suspicious magic shop.
Or rather, if I had been ordered to ‘absolutely not laugh,’ I’m confident I would have burst out laughing and taken a penalty strike to the rear. I wanted to keep watching, but soon Satsuki turns off the switch.
”Well, it’s something like that,” Satsuki said.
”It’s amazing. Even moving this violently, it functions perfectly, and it doesn’t feel like it’s going to break. What on earth is the inside made of…? ” Aerith asked.
”Umm, it would be a long story if I explained in detail, so I’ll skip most of it, but simply put, there’s a metal rod with high flexibility and durability inside. It’s a metal I was originally researching at the Academy and the Court, but I’m using it in place of the articulated type Kento had envisioned. Since it’s a single rod, the joints won’t come apart, and unless you pass magic through it, it shouldn’t bend from human strength… probably,” Satsuki explained.
This was Satsuki’s greatest contribution to this new product. At the stage she saw my blueprints, she had already envisioned using this metal rod. Actually, she gave me quite a passionate speech about it, which is part of why I decided to go ahead with development. This was before the social parties or the release of the Anal-types.
Finally, the cutting-edge magic technology researched by a court mage has been introduced into our shop’s products. I’m grateful, but I’m worried about the ‘pollution’ of Satsuki’s research achievements. Well, she seems to be having a great time, so there’s nothing for it but to pretend I didn’t notice.
”For now, are you satisfied with the durability? ” Satsuki asked.
”Yes, it seems there’s nothing more to do than actually try it out. The other thing I’m curious about is the waterproofness… how is that handled? ” Aerith asked.
”Oh, yeah. Kento was very particular about that, so it’s quite solid. Even if you submerge either of them, water won’t enter the magic circuits, and they’re made of materials that won’t break even if water happens to seep in,” Satsuki explained.
Aerith nods along to Satsuki’s explanation. Ensuring waterproofness was quite a challenge. Because the ‘Ddo-Buddy’ and switch parts are removable, the main body of the ‘Piston Machine’ is full of gaps.
If that’s the case, if the user sprays a massive amount of fluids or leaks, it could get inside and cause a malfunction or make cleaning difficult. So, we decided to apply ‘Waterproof Magic⁵‘, but since I was still uneasy, I carved the magic circuits so they wouldn’t be erased by water in the first place and filled them with water-resistant ink.
For now, Satsuki and I are the craftsmen for the prototypes, but eventually, we might have to think of a way to mass-produce them. Or maybe hire specialized craftsmen. Well, either way, that’s a conversation for after the product is finished.
”What do you think? Are there any other concerns? ” Satsuki asked.
”Let me see…. There are so many combinations that ‘experiments’ seem like they’ll be hard work, but before that, there is one thing I’d like to ask,” Aerith said.
In response to Satsuki’s question, Aerith turned to face me. Her grey wolf ears are pricked up, and her tail is swaying gently, her expression serious.
”By this point, even I can imagine it. The end goal of the product development you are envisioning, Master. Could it be that this new product is just a stepping stone toward creating the ultimate erotic magic tool…? ” Aerith asked.

Character Insight:
Satsuki demonstrates significant growth as a developer, moving beyond Kento’s original designs to incorporate her own high-level magical research. Her willingness to discuss and handle these tools with academic seriousness shows how much she has embraced her role in the shop. Aerith continues to be the pragmatic voice of the market, focusing on durability and waterproofness, showing her deep understanding of the ‘real-world’ application of these items.

Behind the Scene:
The ‘Wriggle Ddo-Buddy’ represents a shift in the story where the technology becomes increasingly complex, blending the ‘low’ purpose of the items with ‘high’ magical engineering. The term ‘power word’ (パワーワード) used by the narrator is a common Japanese internet slang for a term that has a strong or bizarre impact.
